Coronation Street star Mollie Gallagher talks stunt week

Coronation Street spoilers follow.

Coronation Street star Mollie Gallagher has promised an "emotional rollercoaster" during the show's shock stunt week.

ITV is lining up terror in Weatherfield for Super Soap Week, as a massive storm and the sinkhole prove to be a deadly combination for multiple families on the cobbles.

One of the converging storylines will revolve around Nina trying to talk Abi out of taking drastic action when he returns to town with a gun, intent on taking revenge against Corey.

Speaking ahead of these scenes, Gallagher described her own character Nina as "desperate for justice for Seb and herself" at the beginning of the week.

"Her behaviour is erratic and she flicks between the two, at times she has thoughts of revenge but then there's Roy by her side who’s full of wise words and Nina trusts him so he’s the voice of reason who can hopefully get her back on the right track," the actress said.

"It's a matter of her heart over her head at times but hopefully Roy will make her see sense and that this isn't what Nina's about."

She went on: "She can see Abi's behaving strangely, at times irrationally, and Nina picks up on that. I guess she can see that Abi's thinking what she has at times."

Both remain furious that Corey continues to prosper after being wrongly acquitted for Seb's murder, as he has now been transferred to a German club.

"She can see Corey getting all these opportunities, his life is undeservedly on the up, while Seb is dead and she's suffering with the aftermath of what Corey's done," Gallagher noted.

"It feels like there's no justice, obviously she can't bring Seb back but Corey not being found guilty is devastating. This is just another trigger, she can’t believe it's really happening and hearing and reading all these things about Corey just makes her feel worse and worse."

Gallagher has hinted that Nina and Abi will reach a breaking point during this crisis in Weatherfield, when Abi considers killing Corey.

She previewed: "Nina is on an emotional rollercoaster right now which is understandable after what she's been through but we're going to see some quite erratic behaviour from both her and Abi as they struggle to deal with losing Seb and seeing Corey's life seemingly going from strength to strength.

"The scenes we've been filming are amazing, so atmospheric, the set design is unreal, it's been great to be part of it."

As for what's to come for the trio, Gallagher said: "The storyline has been amazing, to be part of the team telling this story has been such a privilege. It's a journey we've been through and there’s lots more to come yet."

Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm.
